GAS-BURNER.

.To all. whom it 11mg/ concern:

Be it known that I, GEORGE MACHLET, Jr., a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

This invention relates to improvements in burners used for heating purposes, the fuel consisting usually of mixed gas and air under pressure.

The object of the invention is to produce a high degree of heat by means of a relativelysmall burner and to eliminate all liability of if'lame entering the body of the burner and causing an explosion therein.

In carrying out my invention 1 employ a tubular body, a cap, and an intervening screen, having jets which are sufficiently small to prevent lflame from entering the burner. The screen consists in this instance of a notched ring, the notches constituting radial jets for the gas. Projections are also formed on said ring extending up and down therefrom to interlock with both the cap and the tubular body of the burner, and means are provided for detachably connecting said cap, ring, and body.

1n the `accompanying drawings, Figure 1 is an elevation, and Fig. 2a vertical central section of my improved burner, said figures corresponding, respectively, with Figs. 5 and 6 of my application Serial No. 183,333, filed December 1, 1903, Patent No. 766,636, of which this application is in part a division. Fig. 3 illustrates the notches cut deeper at their inlet or interior ends than at their outlet or exterior ends. Fig. 4 shows the ringblank before the notches are cut therein.

The burner comprises a tubular body 1, having a shoulder 2 and a neck 3, the latter inserted within a tube or pipe 4, threaded at its lower end at 5. The burner also com A central screw 3 passes down through a cap within the tube 4 and is threaded into a nut 9, which engages a shoulder 10, formed in the lower end of said tube e1.

The screen 7 consists of a notched solid or thick ring, the notches radiating and formed alternately in its top and bottom surfaces. At 11 and 12 the ring is pressed or stamped or cut to form the notches. These notches form jets for the escaping gas and are preferably made deeper at their inner ends than at their outer ends, as at Fig. 3, in order that the capacity or area of the jets at their inlet ends shall be greater or at least as great as at their outlet ends, thereby to prevent liability of the flame entering through the notches into the interior of the burner, said notches or jets being of course sufficiently small or fine for this purpose.

Around its inner edges the screen or ring is provided with upwardly and downwardly extending projections or teeth 17 1S, which engage within the rims 13 14 and cause the screen to interlock with the cap and the tubular body 1. It will be understood that before the notches are cut the blank 7 a has the form shown at Fig. 4, with upwardly and downwardly projecting in-ternal flanges 17L and 181L and that in cutting the teeth the flanges are also cut through, leaving the proj ections 17 and 18. The cap is also provided with an exterior or border flange 19 immedh ately above the screen, which serves as a spreader for the flames and also as a protector for the screen, preventing dust or other sediment from settling in the corrugations or channels, which would;` tend to choke the same.

My improved gas-burner can be used for many purposes where a high degree of heat is desired and can be made in any desired formround, square, hexagonal, &c. It may be made in different sizes, groups, or clusters, as required, and may be used at ordinary gaspressure or under higher pressure from a blower. The burned-out diaphragme may be replaced at small expense and with great facility by simply disconnecting the screw S and exchanging the worn-out diaphragm for a new one, the projections 17 1S insuring that the new diaphragm shall be set or locked properly between the cap and the body of the burner.

Variations may be resorted to within the scope of the inventionas, for instance, the body of the burner may consist simply of a plain tube 1 without using the head 1. The notched ring or screen may also be used in certain other forms of gas-burners.

Having thus described my invention, I claim- 1. A gasburner comprising a tubular body, a cap therefor, and an intervening screen comprising a ring notched in its top and bottom surfaces and having projections to interlock with both said body and said cap, the notches radiating and forming jets, and being larger at their inlet ends than at their outlet ends. 'j

IOO

2. A gas-burner comprising a tubular member, a cap, and an intervening notched ring, the notches alternating on its top and bottom surfaces, and being outwardly directed, and forming jets, and being deeper at their inlet ends than at their outlet ends, said ring formed with projections to interlock with said cap and said tubular member.

' 3. A gas-burner comprisingV a tubular body having a rim, a cap therefor having av rim, and an intervening notched ring operating as a screen to prevent entrance of flame into said tubular body, the notches being outwardly directed, and formed alternately in the top and bottom surfaces of the ring, projections extending upwardly from the ring and downwardly from the ring to iit within said rims, and means detachably securing said cap and ring upon said tubular body 5 the top notches being close to the bottom notches, so that the vapor issuing from all the notches burns in a single flame.

4. A gas-burner comprising a tubular body having an interior fixed nut, a cap for said body, the cap having a rim of the same diameter as the tubular body, a notched ring intervening between said cap and body, a screw passing down through said cap and threaded into said nut, and similar proj ections extending both upwardly and downwardly from the ring, to interlock the latter with said cap and said body. Y

5. A gas-burner comprising a tubular body having a rima cap therefor having a rim, an intervening notched ring, said ring having outwardly-directed notches formed alternately in its top and bottom surfaces,

and having similar projections extending upwardly and downwardlyy to fit Within said rims, the latter being similar, a fastening device passing down through said tubular body, and means within the tube engaged by said fastening device.

6. In a gas-burner, a ring having radiating notches, said ring being also provided with a iiange through which said notches are prolonged; said notches serving as jets for the gas, and each extending continuously from edge to edge of the ring, and the notched ilange operating to hold the ring in position on the burner.

7. In a gas-burner, a notched ring having a ilange, the notches radiating and each notch in the ring extending also through the flange, the notches radiating and serving as jets for the gas, each notch larger at its inlet end than at its outlet end.

8. In a gas-burner, a notched ring having top and bottom flanges, the notches formed alternately in the top and bottom surfaces of the ring and each notch prolonged to extend through the flange.

9. In a gas-burner, a notched ring having top and bottom flanges, the notches formed alternately in the top and bottom surfaces of the ring and each notch prolonged to extend through the flange, the notches radiating and serving as jets for the gas, and each notch larger at its inlet end than at its outlet end.
